Answer:
0.76
Step-by-step explanation:
[tex]There\ are\ two\ situations:\ 1.\ A\ is\ obtained\[/tex]
[tex]2.\ A\ is\ not\ obtained\ but\ B\ is\ obtained\[/tex]
[tex]1:P=0.6[/tex]
[tex]2:P=(1-0.6)[/tex] × [tex]0.4=0.16[/tex]
So the probability is [tex]ab+0.16=0.76[/tex]
I hope this helps you

Probability helps us to know the chances of an event occurring. The probability of getting at least one contract is 0.76.
Probability helps us to know the chances of an event occurring. The sum of all the probabilities of an event is always equal to 1. The formula for probability is given as,
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
The probability of not getting A, A' = 1 - 0.6 = 0.4
The probability of not getting B, when contractor does not get A,
A'∩B' = 1 - 0.4 = 0.6
Now, the probability of not getting any of the contract is,
Probability of not getting any contract = P(A') × P(A'∩B')
= 0.4 × 0.6
= 0.24
Now, the probability of getting at least one contract is,
Probability of getting at least one contract
= Total Probability - P(A'∩B')
= 1 - 0.24
= 0.76
Hence, the probability of getting at least one contract is 0.76.
