Liz flips a coin 30 times. The coin lands heads up 21 times and tails up 9 times. Complete each

SSSSS [86.1K]

Answer:

$Pr = 0.50$

Step-by-step explanation:

Given

$n = 30$

$H = 21$

$T = 9$

See attachment for complete question

Required

$P(H)$

The question requires that we calculate the theoretical probability of landing on the head.

This means that, we have to ignore the given data, and we use the following

$S =\{H,T\}$ --- sample space

$n(S) = 2$ --- sample size

$n(H) = 1$ --- occurrence of Head

So, the theoretical probability is:

$Pr = n(H)/n(S)$

$Pr = 1/2$

$Pr = 0.50$
