A box contains 1414 large marbles and 1111 small marbles. Each marble is either green or white. 66 of the large marbles are gree

Luba_88 [7]

Answer:

0.9739

Step-by-step explanation:

We have 1111+1414=2525 marbles, and

44 small white matbles and

1414-66=1348 big white marbles.

So we have 44+1348=1392 white marbles.

The probability to choose small marbles is P(s)=1111/2525=0,44

The probability to choose white marbles is:

P(w)=1348/2525=0,5513.

The probability to choose small and white is:

P(s and w)=44/2525=0,0174

The probability to choose small or white is:

P(s or w)= P(s)+P(w)-P(s and w)=0,44+0,5513-0.0174=0,9739
