Question

A bag contains 30 red tiles, 15 green tiles, and 5 yellow tiles. One tile is drawn and then replaced. Then a second tile is drawn. What is the probability that the first tile is yellow and the second tile is green?
A.
1%
B.
3%
C.
6%
D.
18%

Answer 1

Allright we know that the total number of tiles is 50 so we can assume that if you pick the first tile and its yellow ther is a (5/50) chance to pick it up and then REPLACED meaning that it is put back so you have still 50 tiles to choose from, if then you choose a green tile you have a (15/50) chance of picking it up

(5/50)*(15/50)=0.03 YOU HAVE A 3 PERCENT CHANCE!!!:D
^This is to calculate the probability of picking it in that order)^
