Stats Question - Please Help (simple)

[From: ] [author: ] [Date: 11-11-09] [Hit: ]
.-Probability of a coin falling head up = 0.Probability of 5 coins falling head up = 0.50 x 0.50 x 0.50 x 0.......
"When tossing 5 coins, what is the approximate probability that they will ALL fall head up?"

Please show how you reached your answer, thank youu..

-
Probability of a coin falling head up = 0.50
Number of tosses = 5

Probability of 5 coins falling head up = 0.50 x 0.50 x 0.50 x 0.50 x 0.50 = 0.03125
You could also do 0.50^5 = 0.03125

P(h1⋂h2⋂h3⋂h4⋂h5) = P(h1)*P(h2)*P(h3)*P(h4)*P(h5) = 1/(2^5) = 1/32
