The probability of tossing heads and not rolling 5 is 31/32.
Let us assume a coin is fair and 2-sided.
A coin usually flips heads or tails.
Then to flip heads or tails equals 1/2
Consider flipping a coin 5 times.
Since a coin flip has two outcomes, then a coin flip 5 times has 2
5 =32 outcomes.
We may show the outcomes, e.g. use sample space S.
Then (1)S=(H,H,H,H,H),(H,H,H,H,T),…,(T,H,H,H,H),(T,T,T,T,T)
It must follow ∣S∣=32.
A helpful way to see may be S=H, T 5=H, Tx…Hx, T.
What is the formula for probability?
P(S)=1-P(A)
If you see the complement of at least 1 tail means 0 tails or 5 heads, then we must surely see 1 outcome, e.g. all heads.
Then it must follow at least one tail that has 31 outcomes,e.g.32–1=31.
To find or compute the probability, then fevorable possible in outcomes.
It means 31/32,
P(E)=1– 32/1= 32/31
