Given:
A box contains 77 red marbles, 6 white marbles, and 94 blue marbles.
Required:
We need to find the probability to select a marble that is red or white.
Explanation:
Let A be the event that selects a red or white marble.
The total number of marbles in the box = 77+6+94 =177 marbles.
The possible outcomes = the total number of marbles = 177 marbles.
[tex]n(S)=177[/tex]The favorable outcomes = The number of red marbles + the number of white marbles =77 + 6 = 83marbles.
[tex]n(A)=83[/tex]The probability of selecting a red or white marble.
[tex]P(A)=\frac{n(A)}{n(S)}=\frac{83}{177}[/tex]Final answer:
The probability of selecting a red or white marble is 83/177.
