Question

Find the probability that a number selected
at random from 11 to 230 is neither a
multiple of 3 nor multiple of 5.​

Answer 1

Answer:

probability that a number selected  at random from 11 to 230 is neither a  multiple of 3 nor multiple of 5 is 0.93

Step-by-step explanation:

Total numbers between 11 to 230 is 218.

Multiple of 5 and 3 is 15.

Number of multiples of 15 between 11 and 230 is 15.

Thus the probability that a number selected  at random from 11 to 230 is neither a  multiple of 3 nor multiple of 5

          = 1 - probability that a number selected  at random from 11 to 230 is both multiple of 3 and multiple of 5

          = 1 - 15 \ 218

          = 218 - 15    \     218

          = 203 \ 218

          = 0.93
