Answer: A
Step-by-step explanation:
1/3n (variable)
-3 (it says subtracted)
(is less than 6)
(n is less that 27)
Unit rate = price/quantity
= 40/16
=2.5 per pair (2.5/1)
five to the second power is 5x5 which is 25.
two to the fifth power is 2x2x2x2x2 which is 32.
Answer:
P = 1 / 6
Step-by-step explanation:
Given:-
- A deck has 500 cards
- Numbered from 1-500
Find:-
you are asked to pick three cards, one at a time, what's the probability of each subsequent card being larger than the previous drawn card
Solution:-
- Suppose we draw three cards. We don't care what they actually are, irrespective of number.
- Let the three numbers be a, b, c: Such that:
a < b < c.
- The total possible combinations with 3 numbered cards will be:
a b c
b a c
a c b
b a c
b c a
c a b
- We have 6 possibilities for 3 numbered cards. So the probability of of each subsequent card being larger than the previous drawn card would be:
P = 1 / possible combinations
P = 1 / 6
