Answer:
see below
Step-by-step explanation:
Let f = number of friends
all but one friend got 6 pieces and 1 friend got 2 for a total of 50 pieces
6(f-1) + 2 = 50
Subtract 2 from each side
6(f-1) +2-2 = 50-2
6(f-1) = 48
Divide by 6
6(f-1)/6 = 48/6
f-1 = 8
Add 1 to each side
f-1+1=8+1
f=9

Answer:
Step-by-step explanation:
Experimental probability is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed.
Theoretical probability is a method to express the likelihood that something will occur. It is calculated by dividing the number of favorable outcomes by the total possible outcomes.
Experimental: 38 times occurred/ 100 trials = 38/100 = 38%
Theoretical: 1/2 chance a coin lands on heads, 1/2 chance a coin lands on tails. 1/2 = 50%
Onne depends on chance, and one on facts, they are different.
Experimental Probability can vary for flipping a coin
Theoretical Probability will always be 50%
