Working out the expression 7(3ˣ) is first to calculate the value of 3ˣ then multiply the answer to 7.
For example, let x = 2
Then 7(3ˣ) = 7(3²) = 7 × 9 = 63
With the same value of x = 2, calculating 21ˣ = 21² = 441, which isn't the same answer with the expression 7(3ˣ)
Answer:
3
Step-by-step explanation:
1st draw: 5/26
2nd draw 4/25
probability of 2 vowels = 5/26* 4/25
rearrange to make the math easier
= 5/25* 4/26
= 1/5 * 2/13
=2/65
