Can someone help me with this pls.

Find the probability of each event. 13) A basketball player has a 50% chance of 14) A mechanic working under a car requires making each free throw. What is the four different size wrenches from his probability that the player makes exactly toolbox, which contains twelve different two out of six free throws? wrenches. Reaching for his toolbox, he A) 63 grabs four of them at random. What is the 256 24.609% probability that the mechanic has all of the 15 wrenches he needs? B) 128 11.719% 1 A) 7 715 0.14% B) = 0.05% C) 15 2002 23.438% 64 = 1.111% 1 C) D) None of these 495 -= 0.202% 90 D) E) 45 E) None of these 1024 - =4.395% Determine if the sequence is arithmetic. If it is, find the common difference, the 52nd term, and the explicit formula. 15) 23, 18, 13, 8, .. 16) -6, -11, -16, -21, ... A) Common Difference: d = -5 A) Common Difference: d = -1 as =-237 as =-58 Explicit: a =23 - 5n Explicit: a =-6 -n B) Common Difference: d = -4 B) None of these a = -186 C) Common Difference: d = -5 Explicit: a = 22 - 4n a=-261 C) Common Difference: d = -4 Explicit: a =-1 -5n a=-184 D) Common Difference: d = -4 Explicit: a = 24 - 4n do =-210 D) Common Difference: d = -4 Explicit: a = -2 - 4n a=-182 E) Common Difference: d = -3 Explicit: a = 26 -4n a=-159 E) None of these Explicit: a =-3- 3n
