Banana cupcake for dinner makes me wanna go swimming so its set 4 94 322
Answer:
33.04% probability that exactly five of them are black
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the buttons are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
Five black buttons, from a set of 10
Four brown buttons, from a set of 6.
Total outcomes:
Nine buttons, from a set of 16.
Probability:
33.04% probability that exactly five of them are black
The correct answer is that it is 6% higher than the theoretical probability. You can find this because with 2 possible, equal outcomes, the theoretical probability is that you will get heads and tales 75 times. However, since we got heads 84 times in the experiment, we know that it is 6% more than 75.
.93 would have to be the answer because you do the regular calculations, then you divide to find y.
