Question:
Bingo uses the numbers from 1 to 75.If the numbers are pulled and random,what is the probability that the first number is multiple of 5?is not a multiple of 5?
Answer:
75/5=15
There are 15 numbers which are multiple of 5,so there are 75-15=60 numbers which are not multiple of 5.
5,10,15,20,25,30,35,40,45,50,55,60,65,70,75
Probability of multiple 5 is 15/75=1/3
Probability of not multiple of 5 is 60/75=4/5
