Question

A computer randomly picks a number from the group 75, 76, 77, 78, 79. What is the probability the number selected is greater than 78 or even? Enter your answer, as a decimal, in the box.

Answer 1

For the answer to the question above, I think since there are only two numbers in the given sequence that are even or greater than 78. I think the probability would be 0.4

I hope this helps you somehow. Have a nice day!

Explanation:

Answer 2

The chance to pick something= valid picks/all possibilities
of your numbers 76, 78 and 79 fulfill "even or greater than 78" and you have 5 numbers in total
chance=
`(3)/(5)`=
`(6)/(10)`=0.6

So there is a 60% probability to pick a number which is even or greater than 78
