a bag contains 40 slips of paper numbered 1-40. if one is randomly chosen, what is the probability of not choosing a multiple of 3 (give each answer as a fraction in simplest form)

80% probability of not choosing a multiple of five

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes:

In this problem, we have that:

There are 40 numbers between 1 and 40.

Multiples of 5 are: 5,10,15,20,25,30,35,40

So there are 8 numbers that are multiple of 4 and 40-32 = 8 which are not multiples of five.

So

32/40 = 0.8

80% probability of not choosing a multiple of five

Step-by-step explanation:

so there are 13 multiples of three and there's 40 numbers in total. 40 times 2.5 is 100. you do 13 times 2.5 which equals 32.5 percent chance of getting a multiple of three. so you do 100 minus 32.5= 67.5 percent chance of not getting a multiple of three.

Hope this helps:)

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

Volume of rectangular prism=length * width * height

Given,

length=3/8cm

breadth=5/8cm

height=7/8cm

therefore volume=(3/8)*(5/8)*(7/8)

                           =105/512 cm3
