In college math class of 50 student are 23 are boys 27 are girls on the final exam 15 boys and 14 girls made an a. what is the probability of choosing a boy or an girl a student is choosen at random from the class

The probability of choosing an A student is 58% (0.58 or 29/50)

Step-by-step explanation:

The fact that 23 students are boys and 27 are girls is irrelevant to the question so we can ignore that.

There are 50 students in all and out of these students 15 boys and 14 girls made an A.

We can first add 15+14 which equals 29. So 29 students out of 50 made in A on the exam.

29/50 equals 0.58 or 58%.

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
