Answer:

5/36

Step-by-step explanation:

Total number in the universe = 4 + 3 + 5 = 12
Probability of selecting a green (first time) = 4/12
Probability of selecting a yellow (2nd time) = 5/12
P(gr then yellow) = 4/12 * 5/12 = 20 / 144
This reduces to 5/36

Laura is bowling 5 games. Her first 4 scores were 118, 128, 124, and 98. To end up with an average score of at least 123.2, what

BartSMP [9]

Answer:

148

Step-by-step explanation:

Average = sum of numbers /total numbers

let x = 5th number

123.2 = (118+ 128 + 124,+ 98 + x) / 5

123.2 = (468 + x) / 5

Multiply both sides by 5

616 = 468 + x

x = 148
