Answer:
12.5
Step-by-step explanation:
4.5 - 3 = 1.5, so 11 + 1.5 = 12.5
Answer:
the area of the shape is 8cm
Answer:
x = 5
Step-by-step explanation:
1. 8 (x + 2) = 56 Distribute the 8
2. 8x + 16 = 56 Subtract 16 from both sides
3. 8x = 40 Divide both sides by 8
4. x = 5
Saying that the result is "at most" one tail means that there can be zero or one tail.
Consider the sample space S, which is the set of all possible outcomes: S = {TTT, TTH, THT, HTT, THH, HTH, HHT, HHH}. Therefore: S = 8.
Now, consider the event space E, which is the set of successful outcomes: E = {TTT, TTH, THT, HTT}. Therefore: E = 4.
The probability will be:
p = E / S = 4 / 8 = 0.5
Hence, when <span>three coins are tossed the probability that the result is at most one tail</span> is 50%.
