slega [8]

0.088

Step-by-step explanation:

The total number of balls in the urn is;

8 +  5 = 12

Because the pink balls are 8, then the probability of picking a pink ball from the urn is;

8/12

To get the probability that all 6 balls drawn from the urn are pink, we will use the AND probability rule of the mutually exclusive events which means we’ll multiply the probabilities of each of the six pink balls;

8/12 * 8/12 * 8/12 * 8/12 * 8/12 * 8/12

= 0.088

for a fixed voltage, the current in an electrical circuit varies inversely as the resistance in the circuit. If a certain has a
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
