Answer:
Step-by-step explanation:
When two dice are rolled, the sample space is
In total, 36 outcomes
First, find the probability that the sum is 10 or greater:
All favorable outcomes
10:
11:
12:
In total, 6 outcomes.
The probability that the sum is 10 or greater is
Use the complement rule to find that the probability that the sum of the dice is less than 10:
12 is composite
10 is composite
7 is prime
13 is prime
25 is composite
40 is composite
63 is composite
23 is prime
39 is composite
84 is composite
150
area of your base (bh/2) 3x8/2 = 12
2 bases = 24
3 faces ---- Face1 - 7x5= 35 ------Face2 - 7x5 = 35 ------Face3 - 8x7 = 56
24 + 35 + 35 + 56 = 150
