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:

Compute the probability of getting at least 15 heads as follows:
P (X ≥ 15) = 1 - P (X < 15)
![=1-\sum_{x=0}^{x=14} P (X=x)\\=1-\sum_{x=0}^{x=14} [{26\choose x}(0.30)^{x}(1-0.30)^{26-x}]\\=1-0.9970\\=0.0030](https://tex.z-dn.net/?f=%3D1-%5Csum_%7Bx%3D0%7D%5E%7Bx%3D14%7D%20P%20%28X%3Dx%29%5C%5C%3D1-%5Csum_%7Bx%3D0%7D%5E%7Bx%3D14%7D%20%5B%7B26%5Cchoose%20x%7D%280.30%29%5E%7Bx%7D%281-0.30%29%5E%7B26-x%7D%5D%5C%5C%3D1-0.9970%5C%5C%3D0.0030)
Thus, the probability of getting at least 15 heads in 26 tosses is 0.0030.
