Answer:
The probability is 0.2356.
Step-by-step explanation:
Let X is the event of using the smartphone in meetings or classes,
Given,
The probability of using the smartphone in meetings or classes, p = 51 % = 0.51,
So, the probability of not using smartphone in meetings or classes, q = 1 - p = 1 - 0.51 = 0.49,
Thus, the probability that fewer than 5 of them use their smartphones in meetings or classes.
P(X<5) = P(X=0) + P(X=1) + P(X=2) + P(X=3)+P(X=4)
Since, binomial distribution formula is,
Where,
Here, n = 11,
Hence, the probability that fewer than 5 of them use their smartphones in meetings or classes
First you had to add by seven from both sides of equation form.
Then simplify by equation.
Next, you multiply by two from both sides of equation form.
And finally, simplify by equation.
Final answer:

Answer:
Step-by-step explanation:
1 × a = a
a² = a*a ; a³ = a*a*a .....
