Answer

Explanation:

Step1: Calculate total frequency

$355 + 294+355 + 263+278=1545$

Step2: Calculate probability for Psychic Healing

$P(\text{Psychic Healing})=\frac{355}{1545}\approx 0.23$

Step3: Calculate probability for ESP

$P(\text{ESP})=\frac{294}{1545}\approx 0.19$

Step4: Calculate probability for Ghosts

$P(\text{Ghosts})=\frac{355}{1545}\approx 0.23$

Step5: Calculate probability for Astrology

$P(\text{Astrology})=\frac{263}{1545}\approx 0.17$

Step6: Calculate probability for Channeling

$P(\text{Channeling})=\frac{278}{1545}\approx 0.18$

Answer:

Phenomenon Frequency Probability
Psychic Healing 355 0.23
ESP 294 0.19
Ghosts 355 0.23
Astrology 263 0.17
Channeling 278 0.18
