Question

A spinner is divided into five equal sections labeled 1, 2, 3, 4, and 5. Another spinner is divided into two equal sections labeled A and B. Nigel will spin each spinner one time.

How many of the possible outcomes have a number less than 3 or an A?

A.) 9
B.) 5
C.) 7
D.) 2

Answer 1

• D) 0.2

-------------------------

Spinner 1

1 and 2 are less than 3 and it is out of possible 5.

The probability of less than 3 is:

• 2/5 = 0.4

Spinner 2

It has two equal sides and the probability of any is:

• 1/2 = 0.5

Total outcome of both events is:

• 0.4*0.5 = 0.2

The matching choice is D.
