Astudent is taking two courses, history and math. the probability the student will pass the history course is 0.60, and the probability of passing the math course is 0.70. the probability of passing both is 0.50. what is the probability of passing at least one

The probability that students will passing at least on course=0.80.

Step-by-step explanation:

We are given that  a student is taking two courses, history and math.

The probability the student will pass the history course =P(A)=0.60

The probability that the student will pass the math course=P(B)=0.70

The probability that the students will pass the both course=

We have to find the probability that student passing at least one course.It means we have to find the probability of

We know that formula

Using the formula we get

The probability that students will passing at least on course=0.80.

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
