Answer:
P(4) =p(x=4) = 0.205078
Step-by-step explanation:
<u>Explanation</u>:-
The probability of x successes in the n independent trials of the experiment.
Given n=10, p=0.5,
By using Binomial distribution

Given the p = 0.5
q=1-p =1-0.5=0.5

we will use formula




on calculation, we get
P(X=4) = 0.205078
Answer: m = 3.3 mol·58.326 mol = 192 g
Step-by-step explanation: molar mass of substance is
M= (24.31+ 2·1.008 + 2·16) g/mol = 58.326 g/ mol.
Amount of substance n = m/M and mass m = n·M
5/6 + 1/4
multiply the denominators and numerators in order for equation to have the same denominators to help solve.
20/24 + 6/24
= 26/24
= 13/12

Answer:
Kato must write 12 pages of the report
Step-by-step explanation:
We have given that total number of pages in report = 20
It is given that Kato must write 60 % of the that report tomorrow
We have to find the number of pages which kato write tomorrow
So number of pages which kato write tomorrow 
So kato must write write 12 pages of the report tomorrow because 60 % of 20 is 12
Answer:
<em>The probability of getting exactly 2 of the cards are spades out of 6 cards will be </em><em>0.315</em>
Step-by-step explanation:
6 cards are drawn at random from a standard deck of 52 cards.
The number ways 6 cards can be drawn from a deck of 52 cards will be,

In a deck of 52 cards, 13 cards are of spades. So drawing 2 spades out of 13 is,

As exactly 2 must be spades, so the remaining 4 cards must be drawn from other 39 cards of other suits. This can be done in,

The probability of getting exactly 2 of the cards are spades out of 6 cards will be,
