Answer: 3/5
Step-by-step explanation:
Probabilty of blue tiles: 12/20 =3/5
Probability of letter b tiles: 10/20= 1/2
How to get the denominator?
4+6=10
2+8=10
10+10=20
Answer:
70%
Step-by-step explanation:
Let's list the 4 types of tiles by color and letter:
4 blue tiles with A
6 red tiles with A
2 red tiles with B
8 blue tiles with B
total number of tiles: 4 + 6 + 2 + 8 = 20
Number of tiles that are either blue or have the letter B (lines in bold above) = 14
p(blue or B) = 14/20 = 7/10 = 7/100 = 70%
