Break downs occur on a 20-years-old car with rate λ= 0.5 breakdowns/week. the owner of the car is planning to have a trip on his car for 2 weeks. what is the probability that there will be no breakdown on his car in the trip? [ the rate = ? per two weeks]

0.3679

Step-by-step explanation:

The formula for Poisson distribution  :-

Let x be the number of breakdowns.

Given : The rate of breakdown per week :  0.5

Then , for 2 weeks period the number of breakdowns =

Then , the probability that there will be no breakdown on his car in the trip is given by :-

Hence, the required probability : 0.3679

the answer on e2020 is

3/5

4/3

step-by-step explanation:

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
