Answer:3/20
Step-by-step explanation:
Heads=Boy
Tails=Girl
If the first 3 students are boys, all 3 coins must be heads.
Because in 3 of these experiments, the coins all land on heads, and there are 20 experiments completed, 3 out of the 20 experiments are 3 boys; 3/20.
Hmmmt that’s a good question
Is it subtract by 2? So I think it would be 27,25,23,21, 19
Correlation coefficient is always between -1 and +1. So it cannot be +2.3
