This is a binomial probability experiment. Each trial is independent of one another, ie each roll is independent. The probability of getting an even number is 3/6 = 1/2 = 0.5 and that probability does not change from roll to roll. Furthermore, the value of n is fixed and not infinitely large. Lastly, each trial outcome comes down to two choices: either you get an even number, or you don't. So we've met the requirements of a binomial probability distribution.
The values of n, p and q are:
- n = 30 = sample size
- p = 0.5 = probability of getting an even number
- q = 0.5 = probability of not getting an even number.
You need to find the angle measurements of the triangle.
The angle supplementary to 128 measures (180 - 128 =) 52 degrees.
Using the corresponding and supplementary property because lines m and n are parallel, you know that the highest (in location) angle of the triangle measure 90 degrees.
A triangle's total angle measurements add up to 180 degrees. Subtract the other two known angles from 180. 180 - 52 - 90 = 38. The third (right side) angle of the triangle measures 38 degrees.
Now, using the supplementary angle theorem, you can find angle a, which is supplementary to the third angle on the triangle. 180 - 38 = 142.
Angle a measures 142 degrees.
That should be the final answer. If you need help with the distribution process I can explain that separately if needed. If not, hope this helps!
