Answer:
Step-by-step explanation:
The collector has 160 movie posters and 120 band posters.
She wants to sell 24 movie posters but still have her poster collection maintain the same ratio of 160:120.
Total ratio = 160 + 120 = 280
If she sells 24 movie posters, it means
24 = 160/280 × x = 160x/280
Where x = total number of movie posters and band posters sold
24 × 280 = 160x
160x = 6720
x = 6720/160 =42
Number of band posters that she should sell = total number of both posters - number of movie posters.
Number of band posters that she should sell = 42-24 =18
Answer:
144/441
Step-by-step explanation:
There are 18+24=42 total socks
There are 24 black socks
So the probability is (24/42)*(24/42)=12/21 * 12/21 = 144/441
