Question 971680: the numbers 1 through 50 are written with red markers on slips of paper while the numbers 51 through 100 are written with blue marker on slips of paper.all the papers are put into a bag and shuffled. one paper is randomly selected.
what is the probability of selecting a number less then 16 or a number written in red? find the probability of a number written in blue of multiple of 5 Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Or probabilities are the sum minus double counting.
Probability <16 =0.15
Probability of red =0.5
Double counting is 0.16
Probability is 0.50, same as selecting one that is red.
Second part is ambiguous. Here are possible solutions:
Blue is 0.5
Blue or multiple of 5 is 0.50 and 0.10 from others not blue that are divisible by 5 =0.60
Blue and multiple of 5 is 0.10
