有正面头脑的机会为15%。 85%的机会出现尾巴。我想看看要花多少个硬币才能翻个头。
每次我抛硬币时,我都想将这个数字放在一个空列表中,说明我掷硬币的尝试次数。
我想将硬币总共翻转100次
def coin_flips(n):
for i in range(n): #for i in the number of coin flips
#will continue until we break
empty_list: []
while True:
#flip coin
flipped_coins = np.random.choice(['tails', 'heads'], p = [0.85, 0.15])
#add count number of flipped cons
n += 1
#if coin lands on heads
if flipped_coins == 'heads':
#add integer to empty list
empty_list += n
#if the coin lands on tails
else:
#flip the coin again until it lands on heads
open_box = np.random.choice(['empty', 'elixir'], p = [0.85, 0.15])
#add the count of coins flipped
n += 1
return empty_list
n = 10_000
答案 0 :(得分:0)
如果您只想掷硬币直到获得正面的次数
def flip_coins(n, head_prob):
flips = 0
heads = False
while not heads:
flips += 1
flipped_coins = np.random.choice(['tails','heads'], p=[1-head_prod, head_prob])
heads = flipped_coins == 'heads'
return flips
如果您随后想要列出所花费的金额:
total_flips = [flip_coins(100, .15) for n in range(10_000)]
