Answer:
(I suppose that we want to find the probability of first randomly drawing a red checker and after that randomly drawing a black checker)
We know that we have:
12 red checkers
12 black checkers.
A total of 24 checkers.
All of them are in a bag, and all of them have the same probability of being drawn.
Then the probability of randomly drawing a red checkers is equal to the quotient between the number of red checkers (12) and the total number of checkers (24)
p = 12/24 = 1/2
And the probability of now drawing a black checkers is calculated in the same way, as the quotient between the number of black checkers (12) and the total number of checkers (23 this time, because we have already drawn one)
q = 12/23
The joint probability is equal to the product between the two individual probabilities:
P = p*q = (1/2)*(12/23) = 0.261

The “>” has a line underneath it
Answer:
y=-5/2x-3
Step-by-step explanation:
put the 2 points in slope to get -5/2. then use point slope form(y-y1)=m(x-x1) and put -8 in y1, 2 in x1, and -5/2 in m
Answer:
Step-by-step explanation:
<u>As per similarity, the ratios of corresponding sides are same:</u>
- x/120 = 65/50
- x = 120*65/50
- x = 156 ft
*expanded form: 6/10 + 3/100 + 2/1000 (that is not division those r fractions!)
*written: six hundred thirty-two thousandTHS
always put "ths" when it is after a decimal point.
