AleksandrR [38]

1) -16a+3+7a-6 = -9a - 3

2) 14x+8y+12y-20x = 20y - 6x

3) -3(8p-6)+4p = 18-20p

4) (9x+2y-8) - (12x+11 = -3x + 2y - 19

Assume that random guesses are made for seven multiple choice questions on an SAT test, so that there are nequals7 trials, eac

Answer:

$P(X < 4)=0.1335+0.3115+0.3115+0.1730=0.9295$

Step-by-step explanation:

Question assumed: Find the probability that the number x of correct answers is fewer than 4.

1) Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

2) Solution to the problem

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=7, p=0.25)$
