The number of points, x, scored in a game has the probability distribution below. 16 0.4 0.3 0.2 The number of points obtained in one game is independent of the number of points obtained in a second When the game is played twice, the sum of the number of points for both times .could be 0, 1,2,3, or 4. If Y represents the sampling distribution of the sum of the scores when the game is played twice, for which value of Y will the probability be greatest? (A) 0 (B) 1 (C) 2 (D) 3 (B) 4 fied as major if it has sustained winds greater than 110 miles per hour. Based on data s, a meteorologist estimated the following percentages about future storms. storms will originate in the Atlantic Ocean, of which 20% will be classified as major toms will originate in the eastern Pacific Ocean, of which 15% will be classified as

Answer 1

Probability will be greatest for Y=0

for Y=0 ,

X1=0,X2=0 and probability will be 0.4+0.4 = 0.8 which will be highest of all

option a) [answer]
