0.3 or 30%. The probability that Ace pick a banana from a basket that content others fruits is 0.3.
The key to solve this problem is using the equation of probability where n(A) the numbers of favorables outcomes and n the numbers of possible outcomes.
There are in the basket 10 fruits in total (3 bananas + 4 apples + 3 oranges = 10fruits). Then, extract a fruit can occur in 10 ways, this is n. There is only 3 bananas in the basket, so the fruit that ACE will pick be a banana can occur in 3 ways out of 10, so 3 is n(A).
Solving the equation:
Answer:
x=5 and x=-11
Step-by-step explanation:
(x-2)(x+8)=39
Subtract 39 from both sides
Factor:
(x-5)(x+11)=0
Set factors to 0.
x-5 =0
x+11 =0
x=5, x=-11
