Answer:
80%.
Step-by-step explanation:
Given the following probabilities:
- P(Micheal Being admitted to French), P(F)=50%
- P(Micheal Being admitted to Spanish), P(S)=50%
In Probability Theory, when we have BOTH , we mean the intersection of the probabilities. Therefore:
- P(Micheal Being admitted to BOTH French and Spanish),
We want to determine the probability that he will be enrolled in either French or Spanish (or possibly both).
Probability of either A OR B =
From Probability Theory:
The probability that he will be enrolled in either French or Spanish (or possibly both) is 80%.
Answer:
There will be an infinite number of solutions.
Step-by-step explanation:
From the given system of equations, we have to find the solution.
The equations are
........... (1) and
- 3x + 4y = - 20 .......... (2)
Now, simplifying the equation (1) we get
4y = 3x - 20
⇒ - 3x + 4y = - 20
which is nothing but the equation (2).
Therefore, the system of equations (1) and (2) are the same straight line.
Hence, there will be an infinite number of solutions. (Answer)
