Answer:
So the number of total combinations is 24+30=54.
Step-by-step explanation:
We know that Peg has 4 long-sleeve shirts, 5 short-sleeve shirts, and 6 pairs of pants. We assume that she is going to wear a shirt and a pair of pants.
First, we calculate the number of combinations for a pants and long-sleeve shirts. She have 6 pairs of pants and 4 long-sleeve shirts.
We get: 6 · 4 = 24
Now, we calculate the number of combinations for a pants and short-sleeve shirts. She have 6 pairs of pants and 5 short-sleeve shirts.
We get: 6 · 5 = 30
So the number of total combinations is 24+30=54.
Answer:
Step-by-step explanation:
She can choose any combination of 3 of the 10 shirts
and any combination of 2 of the 5 pairs of pants.
C(10,3) C(5,2)
= [10! / (7! 3!)] [5! / (3! 2!]
= [10 * 9 * 8 / (3 * 2 * 1)] [5 * 4 / (2 * 1)]
= (5 * 3 * 8) (5 * 2)
= 120 * 10
= 1200 possible combinations of clothes to pack.
