Answer:
175 times
Explanation:
To do this, we can find the probability of the coin landing tails up.
There is 1 desired outcome: Landing tails up.
There are 2 total outcomes: Landing tails up or heads up.
The probability is 1/2 for the coin to land tails up every time.
1/2*350=175
The coin will land tails up 175 times.
