Explanation:
Probability (P) is defined as.
#color(red)(|bar(ul(color(white)(a/a)color(black)(("number of favourable outcomes")/("total possible outcomes"))color(white)(a/a)|)))# There is a total of 20 + 15 + 7 + 8 =50 coins in the jar.
She removes 6 quarters, leaving 50 -6 = 44 coins in the jar.
She removed 6 quarters, leaving 20 - 6 = 14 quarters in the jar.
here the 'number of favourable outcomes' is 14. That is the number of quarters left in the jar.
The 'total possible outcomes' is 44. That is the total number of coins left in the jar.
Hence P(quarter)
#=14/44=cancel(14)^7/cancel(44)^(22)=7/22" in simplest form"#
