Pravesh and Solly usually go to a coffee shop during their lunch break and toss a coin to see who will pay. The probability that Prevesh will pay three days in a row is(adsbygoogle = window.adsbygoogle || []).push({});

(1) 0.025

(2) 0.500

(3) 0.125

(4) 0.015

My attempt (I am not sure if this is right)

X= number of days that Prevesh will pay

x-P(x)

0 - 0.250

1 - 0.250

2 - 0.250

3 - 0.250

So I assume that the correct answer is (1)?
