Which of the following describes the probability distribution below? A probability distribution is shown. The probability of 1 is 0.75; 2 is 0.1; 3 is 0.1; 4 is 0.5; 5 is 0.

The answer is: a = about 63.59ft2 for 15

40 & 50 in the right corner are the complementary angles as when placed in a sum (added together) they make 90°

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
