Plis fast

janna flip to pennies 105 times. how many times can she expect both coins to come up heands?

50% (52.5-ish) of the flips can be expected to be heads.

26.25

Step-by-step explanation:

Since the chance of one coin landing on heads is 1/2, we should multiply.

1/2 × 1/2 = 1/4

105 × 1/4 = 26.25

So, the answer is 26.25 times.

Hope this helps!
