Mathew rolls a number cube labeled with the numbers 1−6. He then flips a fair coin. What is the probability that he rolls a 4 an
KATRIN_1 [288]

Answer:

0.083

Step-by-step explanation:

Numbers of Cube = 6

Faces on coins = 2

Therefore, The total outcomes = 6 \times 2 = 12

Now the favourable outcome that he rolls a 4 & flips a head = 1

The probability that he rolls a 4 & flips a head = 1

\frac{Favourable \: Outcome}{Total \: Outcome}

=> The probability that he rolls a 4 & flips a head = \frac{1}{2}  = 0.83333/ approx. 0.83

Therefore, The probability that he rolls a 4 & flips a head = 0.083

First you need to get rid of the parenthesis by distributing the 0.6 to each term inside.
(0.6)(10n) + (0.6)(25) =10+5n
6n +15 = 10+5n subtract the 5n on both sides and subtract 15 from both sides
6n-5n = 10-15
