Question

please solve the questions of probability​

Answer 1

Answer:

1) 1.5

2) 1/4

Step-by-step explanation:

1) Probability of an event must lie between 0 and 1, both included. As 1.5 is greater than 1, it is not possible for it to represent probability.

2) There are 25 prime numbers in between 1 and 100 (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97), so we know it is 25/100. We can simplifiy that, leaving us with 1/4.

Answer 2

(1) B) 1.5 (The probability of a given event lies between 0(impossible) to 1(sure).   No probability can come beyond that. Since 1.5 > 1, it cannot be used to represent probability. )

(2) C) 1/4 (For the explanation please refer to the attachment... )
