Please help me determine the volume of this triangular prism. c;

115 ft

Step-by-step explanation:

Volume of a triangular prism = × base × height × length

Base =2ft

Height = 10ft

Length = 11.5ft

= × 2 ×  10 × 11.5

= 115 ft

The first urn has 8 white balls and 8 yellow balls
There are 16 balls in all, in which 8 are white.

8/16, or 1/2, is the probability from the first urn.

The second urn has 10 white balls and 3 yellow balls
There are 13 balls in all, in which 10 are white

10/13, is the probability from the second urn.

multiply the two fractions together: 

10/13 x 1/2 = 10/26

10/26 simplified = 5/13

5/13, or D is your answer

hope this helps
