The number of members before the entry of two new participants was 6, because before they had 20 yards and after their entry each one had 15 yards.
<h3>How to calculate how many members there were?</h3>
To figure out how many members there were, we must try different numbers until we find which number matches the information. In this case, it can be affirmed that there were 6 members, that is to say that each one had 20 yards.
Now, knowing that 2 more members joined, we must divide 120 by 8 to check the information in the statement.
According to the above, the number of members at the beginning was 6.

The outcome A="At least one" means {1,2,3,4,5......n} where n is the maximum possible outcome.
The only other outcome (B) left (i.e. the complement of the above event "at least one") is (B)={0}.
Therefore, by Kolmogorov's second axiom, A and B are complements, and
P(A)+P(B)=1
therefore
P(A)=1-P(B), or in words,
Probability of outcomes of "at least one" is the complement of the outcome of "0" item.

Answer:
one pound of apple cost $2.5
Step-by-step explanation:
Let the amount they both spent at the grocery store be y and x be the price of apples per pound.
Since Tara bought 5 pounds of apples, 5x = y (1) and Ashley bought 3 pounds of apples and $5 worth other groceries, 3x + 5 = y (2).
Equating both expressions, 5x = 3x + 5
collecting like terms,
5x - 3x = 5
2x = 5
dividing both sides by 2, we have
x = 5/2
x = 2.5
So one pound of apple cost $2.5
