If pointer 1 is spun and then
If pointer 1 is spun and then pointer 2 is spun, determine theprobability of the pointers landing on a color other than
yellow on the first spin and a color other than red on thesecond spin. |
Pointer 1
Pointer 2 |
pointer 1 has 2 sections 50% red and 50% yellow.. pointer 2 has3 sections 50% blue and 25% red and 25% yellow
Answer:
P(color other than yellow on the first spin and color other thanred on the second spin) = P(color other than yellow on the firstspin) * P(color other than red on the second spin)
= (1 – P(yellow on first spin)) * (1 – P(red on second spin))
= (1 – 0.5) * (1 – 0.25)
= 0.375 (ans)
