What is the probability of selecting a number at random from the numbers 1 to 24 that is not divisible by 3?

Answer 1

Hazel Anglin

#2/3#

Since #24# is divisible by #3# the number of numbers between 1 and 24 that are divisible by #3# is:

#24/3 = 8#

Hence the probabliity of selecting a number at ramdom that IS divisible by #3# is:

#8/24 = 1/3#

#:.# the probability of selecting a number that IS NOT divisible #3# is:

#1-1/3 =2/3#
