Answer : 25/51
The probability of drawing two red cards without replacement is 25/102 , and the probability of drawing one red card is 1/2 .
probability(drawing a second red card, given that the first card is red)
= Probability (drawing two red cards without replacement) divide by probability (drawing a one red card)
probability(drawing a second red card, given that the first card is red)

Answer:
66°
Step-by-step explanation:
When a radius(diameter in this case) is perpendicular to a chord, it bisects the chord and the arc formed by the chord. Because of this, we can say mHJ is equal to mKJ. We can write an equation:
mHJ = mKJ
and substitute:
x + 20 = 6x - 45
20 = 5x - 45
65 = 5x
x = 13
mHK is the sum of mHJ and mKJ, we can write mHK as the expression:
x + 20 + 6x - 45
7x - 25
We can substitute x:
7(13) - 25
91 - 25
66°
Answer:
x = 15
Step-by-step explanation:
Given
5(x - 10) = 25 ( divide both sides by 5 )
x - 10 = 5 ( add 10 to both sides )
x = 15
65 (child) + 260 (adult) + 175 (senior) = 500 total tickets
260 / 500 = 0.52
[change 0.52 to a decimal by moving the decimal to the left twice]
