This year Rachel watched 60 movies. She thought that 57 of them were very good. Of the movies she watched, what percentage did she rate as very good?

95%

Step-by-step explanation:

The percentage that Rachel rated as very good is calculated as:

The number that she thought was very good/ Total number of movies × 100

The number that she thought was very good = 57 movies

Total number of movies = 60 movies

Hence,

57/60 × 100

= 95%

The percentage that Rachel rated as very good is 95%

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
