Question $2$

$1\mathrm{.}2$

My old school gaming console will start up $75\%$ of the time, the rest of the time will just go to a blue screen. If I try to start up the console $20$ times and letting represent the number of times the console successfully starts up$,$ what would the correct notation to indicate the probability that fewer than $5$ of the times I try start it up$,$ it works?

$P(r5)$

$P(r5)$
