Question

A stack of cards is numbered 1 to 21. Leilani pulls one card from the stack. What is the best approximation for the probability that the card is a multiple of 5?

Answer 1

Answer:

The approximation is 0.2( real value is 0.19)

Step-by-step explanation:

In this question, we are to calculate the best approximation if in a pack of cards labeled 1 to 21 , the card selected is a multiple of 5

First we know that the total number of options in our sample space is 21; from 1 to 21

now let’s get the multiples of 5. we have 5,10,15 and 20

The probability of selecting a multiple of 5 is thus; 4/21 . This can be approximately be said to be 0.2 ( actual value is 0.19)
