The mode is 55

i found this by doing

3(45) - 2(40)

to find the mode when given just the median and mode always use the formula of 3(median) - 2(median) hope this helped!

Gavin rolls a fair dice 48 times.<br> How many times would Gavin expect to roll an even number?
pantera1 [17]

Answer: The number of times Gavin expect to roll an even number =24

Step-by-step explanation:

Given: Numbers of a fair dice = 1, 2, 3, 4, 5, 6

even numbers = 2, 4, 6

odd numbers = 1, 3, 5

Probability of getting an even number = \dfrac{3}{6}=\dfrac12

If Gavin rolls a fair dice 48 times.

Then, the number of times Gavin expect to roll an even number = 48\times\dfrac12=24

Hence, the number of times Gavin expect to roll an even number =24
