Answer:
{1,6}
Step-by-step explanation:
the second box is always where the y values/range are
7/12 is greater than 1/3 but less than 2/3.
<span>in order to find if this is true, you need to find the common denominator which is 12. in order for 1/3 to have a denominator of 12, you need to multiply by 4. but we all know the rule. whatever we do to the bottom needs to be done to the top, so 1/3 is = 4/12. 7/12 is greater than 4/12. we do the same to 2/3 and multiply the denominator by 4 and the numerator by 4 as well, and the result would be 8/12. if we compare, 7/12 is less than 8/12.</span>
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
