10)

Three rotten eggs are mixed with 19 good ones. One egg is chosen at random. what is the probability of choosing a rotten egg

Answer:_______________

Four rotten eggs are mixed with 11 good ones. One egg is chosen at random. what is the probability of choosing a rotten egg

Answer: $\frac{4}{15}$

SOLUTION 1 :

Given number of good eggs = 11

Number of rotten eggs = 4

Total number of eggs, n(S) = 11 + 4 = 15

Let (A) be the event of choosing a rotten egg = 15

P(A) =	n(A)	=	4	=	$\frac{4}{15}$
	n(S)		15

Two rotten eggs are mixed with 18 good ones. One egg is chosen at random. what is the probability of choosing a rotten egg

Answer: $\frac{1}{10}$

SOLUTION 1 :

Given number of good eggs = 18

Number of rotten eggs = 2

Total number of eggs, n(S) = 18 + 2 = 20

Let (A) be the event of choosing a rotten egg = 20

P(A) =	n(A)	=	2	=	$\frac{1}{10}$
	n(S)		20

Three rotten eggs are mixed with 10 good ones. One egg is chosen at random. what is the probability of choosing a rotten egg

Answer: $\frac{3}{13}$

SOLUTION 1 :

Given number of good eggs = 10

Number of rotten eggs = 3

Total number of eggs, n(S) = 10 + 3 = 13

Let (A) be the event of choosing a rotten egg = 13

P(A) =	n(A)	=	3	=	$\frac{3}{13}$
	n(S)		13

Four rotten eggs are mixed with 14 good ones. One egg is chosen at random. what is the probability of choosing a rotten egg

Answer: $\frac{2}{9}$

SOLUTION 1 :

Given number of good eggs = 14

Number of rotten eggs = 4

Total number of eggs, n(S) = 14 + 4 = 18

Let (A) be the event of choosing a rotten egg = 18

P(A) =	n(A)	=	4	=	$\frac{2}{9}$
	n(S)		18

Four rotten eggs are mixed with 15 good ones. One egg is chosen at random. what is the probability of choosing a rotten egg

Answer: $\frac{4}{19}$

SOLUTION 1 :

Given number of good eggs = 15

Number of rotten eggs = 4

Total number of eggs, n(S) = 15 + 4 = 19

Let (A) be the event of choosing a rotten egg = 19

P(A) =	n(A)	=	4	=	$\frac{4}{19}$
	n(S)		19

Two rotten eggs are mixed with 10 good ones. One egg is chosen at random. what is the probability of choosing a rotten egg

Answer: $\frac{1}{6}$

SOLUTION 1 :

Given number of good eggs = 10

Number of rotten eggs = 2

Total number of eggs, n(S) = 10 + 2 = 12

Let (A) be the event of choosing a rotten egg = 12

P(A) =	n(A)	=	2	=	$\frac{1}{6}$
	n(S)		12

Three rotten eggs are mixed with 16 good ones. One egg is chosen at random. what is the probability of choosing a rotten egg

Answer: $\frac{3}{19}$

SOLUTION 1 :

Given number of good eggs = 16

Number of rotten eggs = 3

Total number of eggs, n(S) = 16 + 3 = 19

Let (A) be the event of choosing a rotten egg = 19

P(A) =	n(A)	=	3	=	$\frac{3}{19}$
	n(S)		19

Three rotten eggs are mixed with 15 good ones. One egg is chosen at random. what is the probability of choosing a rotten egg

Answer: $\frac{1}{6}$

SOLUTION 1 :

Given number of good eggs = 15

Number of rotten eggs = 3

Total number of eggs, n(S) = 15 + 3 = 18

Let (A) be the event of choosing a rotten egg = 18

P(A) =	n(A)	=	3	=	$\frac{1}{6}$
	n(S)		18

Three rotten eggs are mixed with 18 good ones. One egg is chosen at random. what is the probability of choosing a rotten egg

Answer: $\frac{1}{7}$

SOLUTION 1 :

Given number of good eggs = 18

Number of rotten eggs = 3

Total number of eggs, n(S) = 18 + 3 = 21

Let (A) be the event of choosing a rotten egg = 21

P(A) =	n(A)	=	3	=	$\frac{1}{7}$
	n(S)		21

10)

Three rotten eggs are mixed with 19 good ones. One egg is chosen at random. what is the probability of choosing a rotten egg

Answer: $\frac{3}{22}$

SOLUTION 1 :

Given number of good eggs = 19

Number of rotten eggs = 3

Total number of eggs, n(S) = 19 + 3 = 22

Let (A) be the event of choosing a rotten egg = 22

P(A) =	n(A)	=	3	=	$\frac{3}{22}$
	n(S)		22
