Answer:
The probability of the heads up on the first three flips and not on the last two flips will be 1/32.
Step-by-step explanation:
As, the probability of head up when one time coin is flipped is 1/2. And it is said in the question that you must get heads in the first three flips.
So, for the first three flips the probability is = (1/2)^3 = 1/8
And for the last two flips you want to get not heads up.
Then, the probability is = (1/2)^2 = 1/4
Hence, your overall probability will be = 1/8 × 1/4 = 1/32 .
First you can find

of 90.
90 x

= 62
Next, you have $62 left and spent

of it. Meaning you have

of 62 left.

As your answer is not a whole number, you could round according to whatever guidelines your homework has given you (for example - rounding to the 2nd decimal place $53.14)

EXAMPE: 1.304 x 10¹ = 13.04
1.304 x 10² = 130.4
1.304 x 10³ = 1,304
1.304 x 10⁴ = 13,040
1.304 x 10⁵ = 130,400
1.304 x 10⁶ = 1,304,000
1.304 x 10⁷ = 13,040,000
