Math Help Please? Easy
1. The table shows the results of rolling a number cube labeled one through six 50 times. Table: http://gyazo.com/79d7eb2113d53b1d41862d286420b290 What's the experimental probability of getting a 3? 0.11 0.22 0.30 0.27 2. Based on the experimental probability predict the number of times you will roll a 5 if you roll the number cube 300 times. 15 27 48 54 3. A school has an equal number of boys and girls. You use a coin to simulate the first three students to arrive at school each day, where "heads" represents boy and "tails" represents girl. The table shows a sample of 20 coin tosses. Table: http://gyazo.com/cfd04a7db5189184e60182310cf7b4b8 Fine the experimental probability that the first three students to arrive at the school are boys. 3/20 1/5 3/10 1/4 4. Fine the experimental probability that two out of the first three students to arrive at the school are girls. 1/5 1/4 2/5 1/8
@zoomiemoo can u answer all of these please!!!

all do my best
For question 1, they rolled 3 11 times out of 50 so the probably it 11/50or .22 answer B
for question 2, the probably of rolling a 5 is 9/50 or 18 %. 18% of 300 is 54 so the answer is D
for question 3, we are looking for the probably that three boys arrive (HHH). We see HHH 3 out of the 20 times for the experimental probability is 3/20 the answer is A
For question 4, we are looking for two T (girls) and one H (boy). I count 8 so the probability is 8/20=4/10=2/5 the answer is C
I hope this helps. If it did I would appreciate a metal.
