Answer:
3
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
There are 6 numbers on a die, one of them is 5 so we expect to get a five one of six times
P (5) = 1/6
If we roll the die 30 times, we expect to get a five 30 * 1/6 = 5 times
Let f=number of flowers in a vase, then:
5f-16=24 add 16 to both sides
5f=40 divide both sides by 5
f=8
So there were 8 flowers per vase in the beginning.
