Question

For example, there are balls marked B1, B2, up to B15; I16, I17, up to I30; and so on (see photo). In Exercises 41–46, assuming one bingo ball is selected at random, determine

the odds against it containing the letter G.

Answer 1

got any ideas how to start this problem.. . ?

Answer 2

I do but it not good il send what I did before

Answer 3

First, I have to know how many balls there are in total. There are 15 B balls, 15 I balls, 15 N balls, 15 G balls, and 15 O balls. That means there are 75 balls in total. Since there are 15 G balls, the chance that the ball selected is a G ball is 15/75 or 1/5. This means, the odds against it is 4/5 (1 - 1/5).

Answer 4

let me ask a straight q-
is this your work ? its mostly complete lol. what else u need help with ?

Answer 5

you have worked that

probability of getting G ball = 1/5
so probability of not getting a G ball = 1-1/5 = 4/5

odds against getting a G ball =
(probability of not getting a G ball) : (probability of getting G ball)

=> 4/5 : 1/5
=> 4 : 1

you can also write it as \(\frac{4}{1} \)

Answer 6

i just used ur work and completed the tiny last bit :D
hope this helps... .

Answer 7

Tank you I guse that what was missing from it

Answer 8

np... this is very key : you need to understand what "adds against" and "odds in favor" means clearly
