Question 168946
The student has a 1/5 chance of getting any certain question right
The sudent wants to repeat this lucky guess 7 times
This is like rolling a 5-sided dice 7 times and getting the same
number each time
The probability is
{{{1/5 * 1/5 * 1/5 * 1/5 * 1/5 * 1/5 * 1/5 = 1/15625}}}
That's my guess, but I'm often wrong on probability
questions, so get another opinion
