Answer:
The probability of drawing 5 gumdrops in 10 picks from the dish is 0.215
Step-by-step explanation:
A hypergeometric distribution is a discrete probability distribution that describes the probability of successes in draws with each draw being a success or failure, without replacement from a finite population size that contains exactly the same objects. The general formula is given as:
where:
h(x) is the probability of x successes,
n is the number of attempts,
A is the number of successes
N is the number of elements
For this problem:
A = 30, x = 5, N = 50, n = 10
The probability of drawing 5 gumdrops in 10 picks from the dish P(x=5) is
P(x=5) = 0.215
The probability of drawing 5 gumdrops in 10 picks from the dish is 0.215
Let X be a random variable representing the weight of
strawberries.
<span>
μ= 12</span>
σ= 2.5
Solution:
<span>
P(X < 10) = P(z < (10 - 12)/2.5) </span>
= P(z < -2/2.5)
= P(z < -0.8)
= 1 - P(z < 0.8)
= 1 - 0.7881
= 0.2119
<span>The answer is letter B.</span>
Answer: 8/9 or .8
Advice for the future, use math w a y next time for stuff like this.
S is 30 degrees :) triangles are 180 degrees and you already know the measure of two, so if you add 85+65 you get 150. the. you subtract 180-150 and you get 30!
