 A group of people has 9 males and 3 females. Find the probability that the first randomly selected person is a female and the second selected person is a female again.

Respuesta :

Answer:

1/22

Step-by-step explanation:

Number of males = 9
Number of females = 3
Total number in group = 12

P(female being first selection) = (no. of females)/(total number) = 3/12 = 1/4

If the first selection is a female then there will be 2 females left for selection and a total of 11 in group

P(female in second selection | first selection is female) = 2/11

P(female on both selections = 1/4 x 2/11 = 1/22
