I think the answer is D. But I’m not sure at all
Wait I’m so sorry, but is this a real question or I’m jus trippin..?
In this question, you are asked the probability for any of the 30 person to have the same birthday. To answer this it will be easier to calculate how much the probability for no one has same birthday. Let say the first person birthday is 1. Then the next person birthday should be other than 1, which mean 364 possible days out of 365 days. The next person should be 363 possible days out of 365 days
Then the calculation for 30 people would be:
(365!/365-30!)/(365^(30)= (365!/335!)/ 365^30= 29.4%
Then the probability of at least two person have same birthday would be: 100%-29.4%= 70.6%

- Given, BD bisects Angle ABC.
- So, Angle ABD = Angle CBD
- Measure of Angle ABD = 9x-7
- Measure of Angle CBD = 6x+2
- Therefore,
Angle ABD = Angle CBD
or, 9x-7 = 6x+2
or, 9x-6x = 2+7
or, 3x = 9
or, x = 9 ÷ 3
or, x = 3
- So, x = 3
- Measure of Angle ABC
= Measure of Angle ABD + Measure of Angle CBD
= [(9x-7)+(6x+2)]°
= [(9×3-7)+(6×3+2)]°
= [27-7+18+2]°
= 40°
<h2><u>ANSWER</u><u>:</u></h2>
x = 3
Measure of Angle ABC = 40°.
