Answer: it’s 1/10
Step-by-step explanation:
Answer:
There are 10 cards in total.
The probability of choosing card with the number 4 is 1/10.
The probability of choosing card with the number 1 is 2/10 = 1/5 (since there are 2 cards with the digit 1 - 1, 10)

108=103e^(5k)
108/103=e^(5k) take the natural log of both sides
ln(108/103)=5k
k=ln(108/103)/5
k≈0.00948
P=103e^(12*0.00948)
P≈115 million (to nearest million)

Answer:
Step-by-step explanation:
<u>Use ratios:</u>
- 30/20 = (x + 5)/(36 - 20)
- 3/2 = (x + 5)/16
- 2(x + 5) = 3(16)
- 2x + 10 = 48
- 2x = 38
- x = 19
