Answer:
The probability distribution is
X : 0 1 2
f(X) : 2/7 4/7 1/7
Step-by-step explanation:
Let x is the number of defective sets purchased by the hotel.
Total number of television sets = 7
Total number of defective television sets = 2
Since there are 2 defective television sets and hotel purchase 3 sets, So, X=0,1,2.
If X=0,

If X=1,

If X=2,

The probability distribution is
X : 0 1 2
f(X) : 2/7 4/7 1/7
The probability histogram is shown below.
Answer:
Step-by-step explanation:
Given a large enough sample size the probability is 100%
If the question is "What is the probability of catching 3 tennis balls in three tosses in mid air. Sample size is 3
0.74³ = 0.405224 or about 41%
Answer:
because 4 + (negative 7) is an equivalent expression, the answer is -3.
Step-by-step explanation:
4 + (-7) = -3
3a + a - 15 = 225 . your substituting b(a-15) into the first equation. <span />
What you need to know for this case is that the calculator is using the scientific notation in two different ways:
Way 1:

Way 2:

Where, in both cases:
a, b: they are real numbers.
Therefore, for the following number:

We have an equivalent way is:

Answer:

The e refers to the exponent to which the base 10 is elevated.
