PIT_PIT [208]3 years ago

Permutations are written as nPx where n is the number of total choices possible and x is the number of choices that will be used. This is calculated as nPx = n! / (n-x)!.
Permutations represent the number of ways we can choose x objects from n possibilities where the order of selection matters.

Taymoor is going to apply for two different jobs. He estimates that
Ostrovityanka [42]

Answer:

0.58

Step-by-step explanation:

The probability that Taymoor gets at least one job is a  sum of probabilities of 3 events:

1.He gets Job 1 (P(1.yes)= 0.3) and doesn't get the job 2 (P(2.not)=1-0.4=0.6)

P(1.yes,2.not)=P(1.yes)*P(2.not)=0.3*0.6=0.18

2. He doesn't get job1 (P(1.not)= 1-03=0.7 ) and gets job2(P2.yes)=0.4)

P(1.not,2.yes)=P(1.not)*P(2.yes)=0.7*0.4=0.28

3. He gets  job1 (P(1.yes)= 0.3 ) and gets job2(P2.yes)=0.4)

P(1.yes,2.yes)=P(1.yes)*P(2.yes)=0.3*0.4=0.12

The resulted probability is P(gets job)= 0.18+0.28+0.12=0.58
