In a game a spinner is spun repeatedly. When the spinner is spun, the probability of it landing on blue is 0.11
Find the probability that the spinner lands on blue
for the first time on the 6th spin,
for the first time before the 6th spin,
exactly 4 times during the first 6 spins,
for the 4th time on or before the 6th spin.
Zac and Izana play the game. They take turns to spin the spinner. The winner is the first one to have the spinner land on blue. Izana spins the spinner first.
Show that the probability of Zac winning is 0.471 to 3 significant figures.
