Answer:
The probability of getting at least 15 heads in 26 tosses is 0.0030.
Step-by-step explanation:
Let <em>X</em> = number of heads.
The probability of getting a head is, P (X) = <em>p</em> = 0.30.
The number of coins flipped is, <em>n</em> = 26.
The random variable <em>X</em> follows a Binomial distribution with parameter <em>n</em> = 26 and <em>p</em> = 0.3.
The probability mass function of a Binomial distribution is:
<h2>Compute the probability of getting at least 15 heads as follows:
P (X ≥ 15) = 1 - P (X < 15)
Thus, the probability of getting at least 15 heads in 26 tosses is 0.0030.
