Answer :
Johnny flipped a coin 450 times. His results are below: Heads. Tails.
we know that
when a coin is flipped
the probability of getting head is [tex] \frac{1}{2} [/tex]
we are given
total number of outcomes =140
so, number of times head comes = probability of getting head*(total number of outcomes)
number of times head comes is [tex] \frac{1}{2} *140 [/tex]
number of times head comes is 70......Answer
