1 answer:
Answer:
The number of boxes = 13
Step-by-step explanation:
Given the weight of the delivery person =160 lb
The weight of each box of books=40 lb
maximum capacity of the elevator=710 lb
Let the max number of boxes of books be x. Now the total weight of the boxes and the delivery person should not exceed the maximum capacity of the elevator.
Therefore the maximum value of x is 13(since it is an integer).

Step-by-step explanation:
Given that special deck of cards has 20 cards. Nine are green, seven are blue, and four are red. When a card is picked, the color of it is recorded. An experiment consists of first picking a card and then tossing a coin
A) Sample space will have Green, Head, or Green, Tail .... Red, head, red, tail
No of elements in sample space = no of colours x no of outcomes in coin toss
= 4x2 = 8
B) A= getting (RT)
P(A) = Prob of getting red card and tail on coin
= P (R) *P(T)
=
C) B be the event that a green or blue is picked, followed by landing a tail on the coin toss
B = getting green card and tail
Getting green card tail is mutally exclusive with red card and tail as there is no common element between green and blue.
D) C= red or green card is picked followed by tail.
Here A and C have a common element as getting red and tail. So not mutually exclusive
