Answer:
P(B/C) = 0.3333
Step-by-step explanation:
let's call B the event that a woman was wearing a belt and C the event that a woman was carrying a purse.
The probability P(B/C) that a woman was wearing a belt, given that the woman was also carrying a purse can be calculated as:
P(B/C) = P(B∩C)/P(C)
Where P(C) is the probability that a woman was carrying purse and P(B∩C) is the probability that the woman was both carrying purse and wearing belt.
So, P(C) is calculated as:
P(C) = 18 / 30 = 0.6
Because there were 30 women that walked by in an hour and of those women, 18 were carrying purses.
At the same way, P(B∩C) is equal to:
P(B∩C) = 6 / 30 = 0.2
Finally, P(B/C) is equal to:
P(B/C) = 0.2/0.6 = 0.3333
Answer:
104 Inches
Step-by-step explanation:
Alyssa's blanket contains 7 pink stripes and 6 white stripes.
Total Number of Stripes =7+6=13
Since each stripe is 8 inches wide.
The width of Alyssa's blanket will be the product of the number of stripes by the width of each stripe.
Therefore:
Width = 13 X 8 Inches =104 Inches
Alyssa's blanket is 104 Inches wide.
Answer:
C
Step-by-step explanation:
It says he walked 2(3/4) miles in 2 hours, and it wants to know how far he walked in 1 mile, which would be that number divided by 2.
2(3/4) is the same as 2.75
2.75/2=11/8
which is equivalent to 1(3/8) miles
