Answer:
a) 1/64
b) 1/4096
Step-by-step explanation:
As you can tell from the example, the exponent of 1/2 is the number of heads in a row.
a) p(6 heads in a row) = (1/2)^6 = 1/(2^6) = 1/64
b) p(12 heads in a row) = (1/2)^12 = 1/(2^12) = 1/4096
_____
<em>Additional comment</em>
The probability of a head is 1/2 because we generally are concerned with a "fair coin." That is defined as a coin in which each of the 2 possible outcomes has the same probability, 1/2. Similarly, a "fair number cube" has 6 faces, and the probability of each is defined to be the same as any other, 1/6. Loaded dice and unfair coins do sometimes show up in probability problems.

Answer:
18 3/4 kg of rice
Step-by-step explanation:
<u>Start</u>
<u>Day 1</u>
- He uses 1 3/4 kg of rice
- 25 - 1 3/4 = 23 1/4 kg remaining
<u>Day 2</u>
- He uses 4 1/2 kg of rice
- 23 1/4 - 4 1/2 = 18 3/4 kg of rice
<u>End</u>
