Question

Suppose you have getting
job chance is o.45 and another chance of second job is 0.55 and chance of getting both job is 0.30.find the probability of getting atleast one job​

Answer 1

The probability of getting at least one job​ is 0.70.

Step-by-step explanation:

The probability of getting the first job is, p₁ = 0.45.

The probability of getting the second job is, p₂ = 0.55.

The probability of getting the third job is, p₃ = 0.30.

The probability of getting at least one of the three jobs is:

P (At least one job) = 1 - P (No job)

                                = 1 - P (neither job 1 nor 2 nor 3)

                                $=1-[(1-0.45)+(1-0.55)+(1-0.30)]\\=1-1.70\\=0.70$

Thus, the probability of getting at least one job​ is 0.70.
