Ganezh [65]

Answer:

Starcraft

a) Probability of losing at most 2 games = 33%

b) Probability of winning at least 4 games = 67%

Step-by-step explanation:

a) To lose 2 out of 6 games, the probability is 2/6 x 100 = 33.333%

b) To win at least 4 games out of 6, the probability is 4/6 x 100 = 66.667%

c) Since Serral is playing 6 games, for her to lose at most 2 of the games is described as a probability in this form 2/6 x 100.  This shows the chance that 2 of the games out of 6 could be lost by Serral.  On the other hand, the probability of Serral winning at least 4 of the 6 games is given as 4/6 x 100.  It implies that there is a chance, 4 out of 6, that Serral would win the game.

What is the variance of the following data? If necessary, round your answer to two decimal places 600,470,170,430,300
Mkey [24]

Answer:

72112885110079700000000000000.00

Step-by-step explanation:

X(mean) = (600470170430300 + 23056 + 22123 + 21704 + 20365) / 5 = 120094034103510

n=5

S²(variance) = ((600470170430300-120094034103510)²+(23056-120094034103510)²+(22123-120094034103510)²*+(21704-120094034103510)²+(20365-120094034103510)²/(5-1)

S² = 72112885110079700000000000000.00
