Q:
# #14-8: A sack contains only purple, green, and yellow beads. If selected at random, the P(purple)= 1/5 and P(green)= 1/10. What is the probability of selecting a yellow bead? Express the probability as a number between 0 and 1.

Accepted Solution

A:

Answer:0.7Step-by-step explanation:The way to solve this is to subtract the two fractions from 1.P(y) = 1 - (1/5 + 1/10)P(y) = 1 - (2/10 + 1/10)P(y) = 1 - (3/10)P(y) = 7/107/10 = 0.7
