Question

Select all the values that cannot be probabilities A.) 1 B.) square root of 2 C.) 0 D.) 0.04 E.) -0.54 F.) 3/5 G.) 5/3 H.) 1.29

Answer 1

B.) square root of 2

E.) -0.54

G.) 5/3

H.) 1.29

Explanation:

A probability of an event is how likely the event is to occur. It is always positive values, between 0% and 100%, or as decimals, between 0 and 1.

A.) 1

Can be a probability

B.) square root of 2

The square root of 2 is 1.41. 1.41 is higher than 1, so square root of 2 cannot be a probability

C.) 0

Can be a probability

D.) 0.04

0.04 = 4%

Can be a probability

E.) -0.54

Negative values cannot be probabilities

F.) 3/5

3/5 = 0.6 = 60%

Can be a probability

G.) 5/3

5/3 = 1.67

Higher than 1, so cannot be a probability

H.) 1.29

Higher than 1, cannot be a probability
