denpristay [2]

Answer:

B and D

The probability that Andy chooses a striped shirt and pair of tan or plaid shorts is:

\frac{3}{4} * (\frac{1}{3} + \frac{1}{3}) = \frac{6}{12} = \frac{1}{2}

Solve for C.<br> 5/4= -4c + 1/4
dybincka [34]
5/4= -4c + 1/4

Inverse operation

\frac{5}{4} = -4c + \frac{1}{4}

- 1/4             -1/4

5/4 - 1/4 = 4/4

\frac{4}{4} = -4c
-4c/-4  = 4/4 ÷ -4/1 

4/4 *- 1/4 = c
-4/8 = c
c = -1/2

Answer:  c = - \frac{1}{2}
