Answer:
Standard deviation = 0.547
Step-by-step explanation:
Given the data
$5 for spade
$10 for any club
$20 for an ace club
Lets assume Probability of getting these cards to be
0.5, 0.20 and 0.30
Therefore, mean would be
Summation (PX) = 5×0.5 + 10×0.2 +20×0.3
Summation (PX)/n= 10.5/35 = 0.3
Standard deviation = √0.3
Standard deviation = 0.547
