Answer:
a) 0.6
b) 0.3
Step-by-step explanation:
Since we are taking 3 from a sample of 5 without replacements, we would have 5 choices for the first pick, 4 choices for the 2nd pick and 3 choices for the 3rd pick. The total possible number of ways to do this is:
5*4*3 = 60 ways
As order does not matter (GLS is the same as GSL), we divide this by the number of ways the 3 picks can be arrange, which is 3*2*1 = 6
So there are 60/6 = 10 possible samples
(a) If the governor is included in the sample, then we only have 4 choices for the 2nd pick and 3 choices for the 3rd pick. And there are also 2 ways to arrange this.
So there are 4*3/2 = 6 possible samples. The probability of this happening is 6/10 = 0.6
(b) If G and A are included, we only have 3 choices for the last pick. So the probability of this to happen is 3/10 = 0.3
3x+x=180
x=45 is the right answer
163.2 is the correct Answer
1700, just use the inverse operation. The problem would look like this ( not inverse operation ) x ÷ 33 1/3 = 51
All you have to do is multiply the two numbers.
51 x 33 1/3 = 1700
Now plug it back in and check
1700 ÷ 33 1/3 does indeed equal 51.
Hey there! :D
Since she walks 3/4 a mile a day, we can multiply that by 4.
3/4= .75
4*.75= 3
She walked 3 miles in 4 days.
I hope this helps!
