Question

Probability! I'm moving up in the realm of Mathematics. Anita and Amy appeared for the same interview. Depending on their qualifications, the probability that Anita will be selected is 5/7 and the probability that Amy will be selected is 2/5

Answer 1

1) The probability that neither of them is selected is:_____________ and ________________

2) The probability that at least one of them is selected is: _____________ and ______________

Answer 2

@Narad @Angle If you two can help just a lil bit I'd be in you're debt.

Answer 3

The probability that Anita is selected is = p =5/7
The probability that Amy is selected is =q= 2/5
The probability that neither of them is selected is =(1-p) or (1-q)
The probability that at least one of them is selected is
either Anita is selected and Amy is not selected = p(1-q)
or Amy is selected and Anita is not selected =q(1-p)

Answer 4

the probability that neither of them is accepted if P(Anita not selected)*P(amy nont selected) if that helps

The probability of either one not being selected is 1-P(selected)

for the second bit, the probability that at least one is selected can be thought of as P(amy selected and anita is not)+P(anita slected and amy is not)+P(both selected)
