Answer:
P(both are red) = 5/18
Step-by-step explanation:
total counters = 9
red counters = 5
P(both red) = P(R1) n P(R2)
5/9 * 4/8 =5/18
5/9 because the red counters are 5 and the total number of counters are 9.
I multiplied by 4/8 because, after selecting the first red counter without replacement, the remaining is 4 and the total decreases to 8.
5x+10
just distribute each value and multiply 5 to each of the values in the parentheses.
Step-by-step explanation:
6/√5 multiply it by √5/√5
6√5 × √5/√5 = 6√5/5

Answer:
13/18
Step-by-step explanation:
4/8 simplyfies to 1/2. 1/2 + 2/9= 9/18 +4/18= 13/18
