Use the distributive property to find 5(18) mentally. a. 110 b. 90 c. 23

90

Step-by-step explanation:

Think of 5(18) as 5(10+8).  This is easily done mentally:  50 + 40 = 90.

The answer is 90. Just simply multiply 5 by 18.

48

Step-by-step explanation:

We assume that the die and coins are non-bias.

If you roll a die once, you have 6 possible outcomes (anything from 1-6).

If you flip 3 coins once, you have 2 possible outcomes for each coin (either heads or tails). Multiply those 3 possibilities (2x2x2), you get 8.

Multiply 8 with 6, and you get 48 possible outcomes in sample space.

*In the sample space shown below, do the same combinations to all roll die outcomes to get the whole sample space (i.e., 2TTT, 3TTT, 4TTT etc.).
