Answer:
11/15 red, 4/15 blue
Step-by-step explanation:
There are 15 marbles in all so that is the denominator.
The numerator is the number of marbles for each color.
So...
11 red marbles / 15 total marbles
4 blue marbles / 15 total marbles
Do 2*3 then do the answer divided by 18 to get the answrr
Answer: 0.01145
Step-by-step explanation:
We use Binomial distribution , where the probability of getting x successes in n trial is given by :-
, p = probability of getting each success in each trial.
As per given
The proportion that a car with a certain protection system will be recovered= p=0.87
n= 8
Let x be the number of cars will be recovered.
Then, the probability that 4 of 8 stolen cars will be recovered:


Hence, the required probability is 0.01145.
The answer is C because you divide the P so you get KP=AR then you finish the rest
