Since the Σ( of all colors )= 100%, OR 1, then:
a) P(GREEN ∪ BLUEU) = P(G) + P(BL) = 8%+6% = 14% or 0.14
Since we have to choose ONE candy and only ONE candy at random, then tey are mutually exclusive: No. Choosing a green and blue M&M is possible
b) P(YELLOW ∪ RED) = P(Y) + P(R) = 18%+18% = 36% or 0.36
SAME ANSWER AS BEFORE: mutually exclusive
c) P(NOT PURPLE), Let's calculate 1st, the probability of having a PURPLE:
P(PURPLE) = 21% or 0.21
And the Probability of NOT having a PURPLE is 1-0.21 = 0.79
Answer:
60 degrees
Step-by-step explanation:
Since all the sides are congruent it is an equilateral triangle and all equilateral triangles have angles of 60 degrees.
Another way to solve it is knowing that if all sides are congruent that means all angles are congruent. Then doing 180/3 because all triangles have 180 degrees and there are three equivalent angles.
Answer:
If Tobey gives the stickers out at random, what is the probability that the first child gets a scratch-n-sniff sticker and the second child gets a zoo animal sticker?
P(zoo 2nd | scratch 1st) = (9/25)(16/24) = (9/25)(2/3) = 6/25
Answer:
150 square feet
Step-by-step explanation:
Area of a rectangle = Length x breadth
1 foot = 12 inches
x feet = 120 inches
length= 15 feet, breadth = 10 feet
Therefore x = 120/12= 10 feet, 120 inches = 10 feet
Area = 15 x 10 = 150 square feet
