you spin the spinner once. what is p(less than 4 or factor of 25)? 4/7 3/8 2/5 3/5

Explanation:

Step1: Identify numbers less than 4

Numbers less than 4 are 2 and 3.

Step2: Identify factors of 25

Factors of 25 are 1, 5, 25. In our spinner, the relevant factor is 5.

Step3: Find unique favorable outcomes

The set of favorable outcomes (less than 4 or factor of 25) is {2, 3, 5}, so there are 3 favorable outcomes.

Step4: Calculate probability

The spinner has 5 sections. Probability $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{3}{5}$.

Answer:

$\frac{3}{5}$
