Answer:
11, 10, 9, 8
Step-by-step explanation:
To find the first 4 terms substitute n = 1, 2, 3, 4 into the expression, that is
12 - 1 = 11
12 - 2 = 10
12 - 3 = 9
12 - 4 = 8
The first 4 terms are 11, 10, 9, 8
If he works for 5 hours he will make 42 1/2 or 85/2!
Answer:
= 2.78% probability it will land on both 2 sides.
Step-by-step explanation:
For each trial, there are only two possible outcomes. Either it lands on 2, or it does not. The probability of the spinner landing on two in a trial is independent of any other trial, which means that the binomial probability distribution is used 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.
One of the six sides is 2:
This means that
If the spinner is spun two times, what is the probability it will land on both 2 sides?
This is P(X = 2) when n = 2. So
= 2.78% probability it will land on both 2 sides.
It would be 23 and 24! YOU'RE WELCOME :)
