Answer:
19.75%
Step-by-step explanation:
Since we are trying to find the probability for a sequence of events then we need to multiply the probability of each event happening separately from each other. Since the probability of it raining on a single day is 2/3 we need to multiply this value with itself 4 times (one for each day).
2/3 * 2/3 * 2/3 * 2/3 = 16/81 or 0.1975 or 19.75%
Therefore the probability would be 16/81 or 0.1975 or 19.75%
<em>For another information, when D > 0, there are 2 real roots.</em>
<em>When D = 0, there is only one real root.</em>
<em>And when D < 0, there are no real roots (also known as imaginary.)</em>
