Let A = the event that the first ball is odd number
and B = the event that the second ball is odd number
In the beginning, there are 25 balls which contain 13 balls of odd numbers. So the probability for the first selection (as to expect you would draw a ball of an odd number) is
P(A) = 13/25
After the selection, the rule does not allow replacement. So, there are 24 balls left containing now 12 balls of odd numbers. So the probability for the second selection (as to expect you would draw also a ball of odd number) is
P(B) = 12/24 = 1/2
Multiplying the two probabilities obtains
P(2 odd numbers) = 13/25 * 1/2 = 13/50
Answer:
Step-by-step explanation:
ahh 30° is the mystery angle . sooo
180-30 = 150 that angle BOA
then the other two angle are each 15°
so then BAX is 90-15=75°
:)
Answer:
2x + 10
Step-by-step explanation:
Answer:
congruent
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
Those are alternate interior angles. Alternate interior angles are the ones that happen at different intersections along the transversal but on opposite sides while inside the lines the transversal goes through. If these lines are parallel, then the alternate interior angles are congruent. Same thing the other way around. Alternate interior angles being congruent implies those lines are parallel.
So we are looking to solve:
3x-2=2x+5
Subtract 2d on both sides:
x-2=5
Add 2 on both sides:
x=7
