Answer:
4/6
Step-by-step explanation:
ok so you have 2/3 for 1 group. so for 2 groups youll just have to add 2/3 + 2/3 and that gives u 4/6
Answer:
5/8 > 4/12
Step-by-step explanation:
We can check this by making their denominators the same.
First find the lowest common multiple of 8 and 12 which is 24.
5x3=15 and 4x2=12
8x3=24 and 12x2=24
--
5/8 = 15/24 meanwhile 4/12 = 12/24
15/24 > 12/24
Answer:
P(X < 4) = 0.5
Step-by-step explanation:
For each question, there are only two possible outcomes. Either it is answered correctly, or it is not. The probability of a question being answered correctly is independent of any other question. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
In this question, we have that:

Find the probability that the number of correct answers is fewer than 4:
This is







So
P(X < 4) = 0.5
Answer: Divide resulting answer by 3
Step-by-step explanation:
After you find the area of the base of the cone and multiplied it by the height of the cone, use the answer for that equation and divide it by 3 to get your final answer.
