Answer:
0.1333 = 13.33% probability that bridge B was used.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Arrives home by 6 pm
Event B: Bridge B used.
Probability of arriving home by 6 pm:
75% of 1/3(Bridge A)
60% of 1/6(Bridge B)
80% of 1/2(Bridge C)
So

Probability of arriving home by 6 pm using Bridge B:
60% of 1/6. So

Find the probability that bridge B was used.

0.1333 = 13.33% probability that bridge B was used.
Answer:
Yes, it costs $18.99.
Step-by-step explanation:
The game is originally $36 and a game 50% off is 36/2 = $18.
The sale price is $18.
The state charges 5.5% tax which means you pay 105.5% of the sale price.
1.055(18) = 18.99
The final total is 18.99 which means Ron's $19 is enough.
