Us In a class of 40 students, 17 have ridden an airplane, 28 have ridden a boat. 10 have
ridden a train, 12 have ridden both an airplane and a boat. 3 have ridden a train only
and 4 have ridden an airplane only. Some students in the class have not ridden any of
the three modes of transportation and an equal number have taken all three.
a.
How many students have used all three modes of transportation?
Solution:
b. How many students have taken only the boat?
Solution:
c.
How many students have not taken all three modes of transportation?
Solution:

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

what do u need to know

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
