Answer:
0.35
Step-by-step explanation:
This probability distribution is shown below:
Pitch 1 2 3 4 5
Frequency 15 20 40 15 10
Probability 0.15 0.2 0.4 0.15 0.1
The probability that the pitcher will throw fewer than 3 pitches to a batter = P(X < 3)
X is the number of pitches thrown. Therefore:
P(X < 3) = P(X = 1) or P(X = 2)
The additive rule pf probability states that if two events X and Y are dependent events, the probability of X or Y occurring is the sum of their individual probability.
P(X < 3) = P(X = 1) or P(X = 2) = P(X = 1) + P(X = 2) = 0.15 + 0.2 = 0.35
The probability that the pitcher will throw fewer than 3 pitches to a batter = 0.35
Answer:
ooohh yeah i kinda suck at geometry lol nearly failed sophomore year last year haha
Step-by-step explanation:
in 3.4653, there is one digit to the left of the decimal point, that is the ones position
in 34.653, there are 2 numbers to the left of the decimal point, the 3 is located in the tens place
so 34.653 is greater than 3.4653
The answer for this question when grouping:
(x+2)(3x^2+1)
