In a recent semester at a local university, 500 students enrolled in both general chemistry and calculus i. of these students, 66 received an a in general chemistry, 73 received an a in calculus, and 33 received an a in both general chemistry and calculus. find the probability that a randomly chosen student received an a in general chemistry or calculus or both.

Step-by-step explanation:

Given: In a recent semester at a local university, students enrolled in both General Chemistry and Calculus. Of these students, received an A in general chemistry, received an A in calculus, and received an A in both general chemistry and calculus.

To Find: Find the probability that a randomly chosen student received an A in general chemistry or calculus or both.

Solution:

Total number of students in university

Total number of students received A in General Chemistry

Total number of students received A in calculus

Total number of students received A in General chemistry and calculus both

Probability that a randomly selected student got A in General Chemistry

Probability that a randomly selected student got A in Calculus

Probability that a randomly selected student got A in General Chemistry and calculus

Probability that a randomly chosen student received A in general chemistry or calculus or both

Hence the probability that a randomly chosen student received an A in general chemistry or calculus or both is

12.5 feet

step-by-step explanation:

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 %
