In the deck of cards, there is a total of 52 cards which comprises of: kings, queens, jacks, 10, 9, 8, 7, 6, 5, 4, 3, 2, and aces.

In the problem, we were asked the probability of less than 5, so it would be Ace, 2, 3, and 4. 5 is not included since the problem didn’t ask less than or equal to.

So 4 cards and we have 4 suits in the deck. So 4 x 4 = 16.

16/ 52 = .31 is the probability.

Tatiana [17]

Answer: 1.75 amps

<u>Step-by-step explanation:</u>

V (voltage) = I (current) · R (resistance)

V = 3.5 (110)

= 385

When Resistance is doubled, the current is cut in half.

V = I R

385 = I (2 · 110)

$\dfrac{385}{220}=\text{I}$

1.75 = I
