# 2. Some board games require you to reduce the number of cards you are holding by half, rounded

#how many cards they have and print out what their hand would reduce to under this rule.

#5. One way to estimate probabilities is to run what is called a computer simulation. Here we will estimate
#the probability of rolling doubles with two dice (where both dice come out to the same value). To
#do this, run a loop 10,000 times in which random numbers are generated representing the dice and
#a count is kept of how many times doubles appear. Print out the final percentage of rolls that are
#doubles.

from random import randint


count =0

#while num <= 1 :
for num in range(1,10000) :
    dice_1 = randint(1,6)
    dice_2 = randint(1,6)
    if dice_1 == dice_2 :
        count  = count + 1
    
print("Final percentage of getting doubles:", (count / 10000)*100)

Final percentage of getting doubles: 16.85
