Answer:
54 gallons of 26 percent green dye and then 54 gallons of 16 percent green dye
The answer is 34 because when I add 14+20 that give me 34
5x = 2x + 9, where 5x > 0 and 2x + 9 > 0 ;
Then, 3x = 9 ;
Then, x = 3 ;
Verify : 5 × 3 = 2 × 3 + 9 ;correct !
5 × 3 > 0 ; correct !
2 × 3 + 9 > 0; correct !
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%.
