Giving a test to a group of students, the grades and gender are summarized below A B C Total Male 19 16 12 47 Female 3 5 8 16 Total 22 21 20 63 Give your answers as a fraction or decimal. If one student was chosen at random, (a) Find the probability that the student got an A. Incorrect (b) Find the probability that the student did NOT get an "A". Incorrect (c) Find the probability that the student was male AND got a "C". Incorrect (d) Find the probability that the student was male GIVEN they got a 'B'. Incorrect (e) Find the probability that the student got a 'A' GIVEN they are female.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
