In probability and statistics, there is an equation used for repeated trials. In this equation, you find the probability of getting 'r' successful events out of 'n' trials. Moreover, you should incorporate the probability of the success per trial. For a 6-sided face, each side has a probability of success of 1/6. On the other hand, the probability of each side not appearing is 5/6, because when you add these two, it would sum up to 1 as always.

Now, the equation for repeated trials is:

Total Probability = n!/r!(n-r)! * p^(n-r) * q^r

where
n = 5 tosses
r = 1 and 2 (since you want to see the probability of a side less than 3)
p = 1/6
q = 5/6

So, you add the individual probability when r=1, and when r=2.

Total Probability = 5!/1!(5-1)! * (1/6)^(5-1) * (5/6)^1 + 5!/2!(5-2)! * (1/6)^(5-2) * (5/6)^2
Total Probability = 50/243 or 20.58%

Of the employees who work at Stalling Printing, 90% attended the safety procedures meeting. If 63 employees attended the meeting
LUCKY_DIMON [66]
There are 70 employees who work at Stalling Printing.

Take note that the 63 employees who attended the meeting represents 90% of the total number of employees working at Stalling Printing. To get the total number of employees or the 100% number of employees, divide 63 by its percentage, 90%.

63/90% or 63 / 0.90 = 70 total number of employees.

Out of 70 employees; 63 employees attended the meeting and 7 employees did not.
