Question

which number can not represent a probability
2/3 1.5 15% 0.7
​

Answer 1

Answer:

1.5 is not possible as probabilty.

Step-by-step explanation:

Given,

a) 2/3 b) 1.5 c) 15% d) 0.7

To find: which number can not represent a probability

Concept: Probability of any event is always 0 or greater than 0 and 1 or less than 1. i.e  0 ≤ P ( event ) ≤ 1

Probablity of sure event is 1.

Probability of impossible event is 0.

Solution:

a) 2 / 3 = 0.67 which is greater than 0 and less than 1. So this probability is possible.

b) 1.5 is greater than 1. So this probability is not possible.

c) 15% = 15/ 100 = 0.15 which is greater than 0 and less than 1. So this probability is possible.

d) 0.7 is greater than 0 and less than 1. So this probability is possible.

Therefore, 1.5 is not possible as probabilty.
