Evaluate the expression shown below and write your answer as a fraction in simplest form.

Ierofanga [76]

Answer:

72 / 5

Step-by-step explanation:

( 12 / 5 ) + ( 6 / 5 )

= ( 12 + 6 ) / 5

= 18 / 5

[ ( 12 / 5 ) + ( 6 / 5 ) ] / ( 1 / 4 )

= ( 18 / 5 ) / ( 1 / 4 )

= ( 18 x 4 ) / 5

= 72 / 5

If you roll one die and flip one coin, what is the probability of rolling a 2 and flipping a head? Why?

Nezavi [6.7K]

Answer:

Probability of rolling a 2 and flipping a head will be $\frac{1}{12}$

Step-by-step explanation:

If we roll one die then probability to get any one side is $\frac{1}{6}$

Therefore, probability to get 2 by rolling the die will be P(A) = $\frac{1}{6}$

Now we flip a coin then getting head or tale probability is $\frac{1}{2}$

Or probability to get head by flipping the coin P(B) = $\frac{1}{2}$

Probability of happening both the events (rolling a 2 and flipping a head) will be denoted by

P(A∩B) = P(A)×P(B)

= $\frac{1}{6}\times \frac{1}{2}$

= $\frac{1}{12}$

Therefore, probability of rolling a 2 and flipping a head will be $\frac{1}{12}$
