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 $\frac{1}{12}$

Zach invested $1500. He earned 23.2% on his investment. Determine how much money he has now.

Alika [10]

To figure out 23.2%, first figure out how much 1% is by dividing 1500 divided by 100=15

Next, multiply the 15(1%) by the 23.2% to figure out how much that is.
23.2 x 15 = 348

Now, you have to add thr investment ($348) to his originsl amount of money ($1500).
$1500 + $348 = $1848

Zach now has $1848
