The probability that john will drive to school is 0.31, the probability that he will ride with friends is 0.12, and the probability that his parents will take him is 0.57. he is not allowed to have passengers in the car when he is driving. what is the probability that john will have company on the way to school? p( john will have company on the way to school is what

P(company) = P(ride with friends) + P(with parents) = .23 + .4 = .63 0r 63%

Step-by-step explanation:

The 3 different case scenarios are independent of one another:.37 + .23 + .4 = 1

P of two of them occurring is found by adding their individual Probabilities

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
