Answer:
a. 0.25
b. 0.50
c. 0.75
Step-by-step explanation:
P(E1) = 0.25
P(E2) = 0.25
P(Es) = 0.25
P(E) = 0.25
a. Since there are 4 outcomes with the same probability of occurring, the probability of E occurring is:

b. The probability of any two outcomes occurring is twice the probability of a single outcome occurring

c. The probability of any three outcomes occurring can be written as 100% minus the probability of the remaining outcome occurring

let's keep in mind that, in the II Quadrant, cosine is negative and sine, is positive.
cosine is adjacent/hypotenuse, however the hypotenuse is simply a radius unit, and thus is never negative, so in the -(2/3) the negative must be the numerator, -2.

Answer:
C
Step-by-step explanation:
Let g(x) be y
From the (1,4)
When x =1 y =?
These (2x)^2
(2 × 1)^2 = 2 ^2 = 4
