Answer

Explanation:

Step1: Determine favorable outcomes

Numbers greater than 4 on a 1 - 6 number cube are 5 and 6. So there are 2 favorable outcomes.

Step2: Calculate probability of single - roll

The total number of outcomes when rolling a number cube is 6. The probability of rolling a number greater than 4 in a single roll is $\frac{2}{6}$.

Step3: Predict number of rolls

She rolls 50 times. To predict the number of times she rolls a number greater than 4, we multiply the probability of a single - roll by the number of rolls. So the equation is $P(\text{number greater than }4)=\frac{2}{6}(50)$.

Answer:

P(number greater than 4)=$\frac{2}{6}(50)$
