Answer 1

34/35 . By taking the L.C.M you will get the answer

Answer 2

Answer:

Step-by-step explanation:

We analyse the question first before solving as follows:

We write down the respective probabilities.

P(Bruce getting ) = The probability of Bruce being selected = 2/5

p(Jack getting) = The probability of Jack being selected = 4/7

We need the probability that both of them get selected.

This is written as follows:

P(Bruce and Jack getting)

This is elaborated as :

= p(Bruce gets) × P(Jack gets)

Doing the substitution we have

= 2/5 × 4/7 = 8/35  

= 8/35

The answer is therefore 8/35
