An interesting approach to learning - in Vietnam, a question about CS: GO was included in the math exam

A fan of playing computer games came to reddit and informed the forum users that teachers in Vietnam included an unusual question about CS: GO in the math exam, which sounds like this:

"The player with the Desert Eagle has collided with the enemy. Every shot he makes with the Desert Eagle has a 50% chance of hitting the opponent. If the shot is accurate, there is also a 20% chance that he will hit the head and kill the target immediately, otherwise it takes three shots to take out an enemy. What is the likelihood that a player can take out an enemy in seven shots? "

Users appreciated the ingenuity of the teachers and their interesting approach to business, which allows them to win over fans to play computer games. In addition, they noted that the task was not easy and tried to solve it.
