Question

Cynthia had a bag containing 2 red, 3 green, 4 purple and 6 blue tiles. What is the probability of drawing a green tile, not replacing it and then drawing a red tile?

Answer 1

Answer: 0.2 ; 0.14

Explanation:

Cynthia had a bag containing

Red tiles= 2

Green tiles= 3

Purple tiles= 4

Blue tiles= 6

Total tiles= 2+3+4+6= 15 tiles

Probability of drawing a green tile:

= Green tiles/Total tiles

= 3/15

= 0.2

Probability of drawing a red tile without replacement will be:

Red tiles/Total tiles

Total tiles will make be 15-1 = 14

= 2/14

= 0.14
