Answer:
Theoretical probability: 50/100 or 50%
Experimental probability: 12/20 or 60%
Step-by-step explanation:
Let's find out both probabilities asked.
Theoretical probability:
In the whole bank, here are 100 coins (20 nickels + 30 quarters + 50 one-dollars), among which there are 50 one-dollar coins. So the probability to pick up a one-dollar coin is 50 out 100, so...
TP = 50/100 or 50%
Experimental probability:
For the experimental probability, we know Jonathan picked out 20 coins, out of which 12 were one-dollar coins, so the probability is 12 out of 20...
EP = 12 / 20 = 60%
22. Suppose that the teacher started recording on a digital camera with an hour available.
She gives 15 minutes introduction. Thus 60 minutes – 15 minutes is 45 minutes.
She still have 45 minutes remaining, now the question is how many minutes will remain if she uses 1 minutes per students.
Since the number of students is not given. It depends on how many students will be there. For example 25 students thus that’s equals to 25 minutes also. So she has a 20 minutes remaining.,
Answer: A 4 side dice.
Step-by-step explanation:
Benjamin has 4 possible homerooms with the same probability. This means that every homeroom has a 1/4 = 0.25 (or 25%) probability of getting chosen.
You could emulate this situation with a 4 sided dice (are like little pyramids) where each side of the dice would represent the selection of one of the homerooms.

Answer:
20 votes
Step-by-step explanation:
You start with the percents: You always start with 100%
100-5=95
Then you multiply
95 x 4
4 is how many votes he received the 2nd time
95 x 4= 380
Then you subtract
380-360= 20
Your Welcome :)
