So I'm doing this math grade recovery for the Using Probability test here's one
At a race car rally, attendees can sit in the bleachers, balcony, or the grass the probability an attendee sitting in the bleachers is 1/4 the probability of an attendee sitting the balcony is 7/16 What is the probability that an attendee will sit in the grass

A) P(grass seat) = 3/4
B) P(grass seat 9/16
C) grass seat) = 5/16
D) P(grass seat 11/16)

Much appreciated

1. Ms. Sue

What do you think is the answer?

2. bobpursley

Pr(bleacher)+pr(balcony)+pr(grass)=1

solve for Pr(grass)

3. ConnexusStudent01

I think the answer is D @ms.sue

4. Ms. Sue

Yes, D.

5. Ms. Sue

D is wrong. Sorry.

16/16 - 11/16 = 5/16
