Question

What is the probability that a randomly chosen marble is red or small?

Answer 1

We have the next formula

`P\mleft(RorS\mright)=P\mleft(R\mright)+P\mleft(S\mright)-P\mleft(RandS\mright)`

P(R)=0.7

P(S)=0.9

P(RandS)=0.6

The probability that randomly chosen marbñe is red or small is

`\begin{gathered} \\ P(RorS)=0.7+0.9-0.6=1 \end{gathered}`
