Given:
Number of blue marbles = 6
Number of red marbles = 4
Number of green marbles = 4
Choose one marble without looking,
To find:
The probability that the selected marble is red or green.
Solution:
For the given problem,
Total outcomes = Total number of marbles
=
=
Favorable outcomes = Number of red or green marbles.
=
=
The probability that the selected marble is red or green, is
Therefore, the probability that the selected marble is red or green, is .
1/3 of 45 is 15.
So 45-15= 30.
1/5 of 30 is 6.
So 30-6=24.
There are 24 houses left to be sold.
F(x) = 1/3 * 4^x.......f(4)....so we sub in 4 for x
f(4) = 1/3 * 4^4
f(4) = 1/3 * 256
f(4) = 256/3 <===
Answer:
5
Step-by-step explanation:
44.75 - 28.50 = 16.25 so 16.25 divided by 3.25 equals 5 and 5 times 3.25 equals 16.25 and 16.25 plus 28.50 equals 44.75 so she bought 5 cards.
You can multiply 2x7 to get 14
